Key Stage 4
Meaning
Transpiration is the process by which water is transported from the roots of a plant to the leaves.
About Transpiration
- In transpiration water evaporates from the leaves and is then replaced by water that is drawn up through the stem from the roots.
- Transpiration is needed to bring a constant supply of water and minerals to the leaf for photosynthesis.
- Water is lost from the plant through the stomata, so it is important for the plant to be able to close the stomata to control water loss.
- If too much water is lost through transpiration the plant may begin to wilt.
Factors Affecting Transpiration
The rate of transpiration is affected by:
- Temperature - High temperatures lead to quicker evaporation of water increasing the rate of transpiration.
- Humidity - High humidity makes it harder for water to evaporate slowing the rate of transpiration.
- Wind - The constant flow of air causes evaporation to happen more quickly increasing the rate of transpiration.
